Dual core CPU 65 degrees?

Recently I have took my laptop apart and taken a look at the Processors and Graphics Card. I noticed when I dissembled it, that the blue stuff on top of the processor (Thermal Grease/Heat Paste) had been damaged and was peeling off. I just put it back on normally, but ever since the laptop has been acting odd. For example, the CPU would just overheat when on standby, and the temperature would go as high as 50 Degrees for no reason. Right now, the temperature is 68 when running several other programs such as Bitdefender update. I can't even play Dragon Age 2 without the laptop randomly shutting down. Ever since I took apart the laptop, it just won't play for more than 10 minutes. The fan is emitting cool air as well, and I've made sure to clear dust. Just the heatsink near the processor is scorching hot. Any Ideas?Dual core CPU 65 degrees?
Any time you take the heat sink off the cpu you need to clean off the old and apply new paste... it is a must, you have broken the bond that allows heat transfer from the cpu to the sink so it will dissapate the heat. If your laptop is shutting down because of that it is a bad thing... damage may all ready have been done. Don't turn it on again until you have cleaned and applied more paste (grease.)
LOL

You shouldn't have dissembled the CPU.

The reason that your computer is shutting down is caused by removal of Thermal Grease.

Buy thermal grease and use it properly and it'll return to normal.Dual core CPU 65 degrees?
50 degrees in not very high but I suspect the laptop is actually getting hotter than that is some areas, you might need to reapply thermal grease. maybe look into better heatsinks and fans for the laptop (newegg.com)
Whenever you remount the heatsink on a processor or graphics chip you HAVE to:



1. Clean off the old Thermal Compound with at least 90% rubbing alcohol.



2. Reapply new thermal compound. You'll either want to apply a paper-thin layer on the processors surface (IHS), or use a B.B. sized drop that's just enough to cover the surface when the heatsink is pressed onto the processor.



When you took off the heatsink and then reapplied it you trapped air-pockets between the 2 surfaces. Air is a poor conductor of heat.



You can find thermal compound a places like Best-Buy or Radio Shack. You may find a higher quality thermal compound at a good computer shop. Arctic Silver 5 will probably be a step-up from whatever you had.Dual core CPU 65 degrees?
ha! Intel CPU? Yeah typical Intel....open the laptop and wipe of the old thermal compound completely and apply some fresh thermal compound on top of the CPU and make sure and spread it out evenly. OK. If it is an Intel CPU you are lucky that it even booted.



I had an embarrassing situation which took place while presenting my PC as my final project at school moments before my presentation i took my PC apart and clean it up and make it look good, but i did not have any thermal compound to replace the old one......that was so embarrassing the PC would only reach windows welcome screen and then immediately shutdown the moment i applied the thermal compound and mount it up the PC was up and running as normal.
